GEORGE NV. KRAMER, OF PEORIA, ILLINOIS, ASSIGNOR TO THE INDIANAMANUFACTURING COMPANY, OF INDIANAPOLIS, INDIANA.

PNEUMATIC STRAW-STACKER.

SPECIFICATION forming part of Letters Patent No. 633,383, datedSeptember 19, 1899.'

r Application filed February 27, 1899. Serial No. 707,046. (No model.)

T 0 all wlwT/t lit 'nuty cancer/t:

Be it known that I, GEORGE W. KRAMER, a citizen of the United States,residing at Peoria, in the county of Peoria and State of Illinois, haveinvented certain new and useful Improvements in Pneu maticStraw-Stackers, of which the following is a specification.

One object of my present invention is to provide a means by which thedust and chaff may be separated from the straw in the operation of apneumatic stacker.

A further object is to take off a part of the pressure from the straw ator just be fore the point of delivery, so that it will 'be thrown outonto the straw-stack with less force when this is desired.

Said invention consists in the use of a suction-fan connected to thetrunk or chute of the pneumatic straw-stacker at a suitable point at ornear its outer end and provided with a discharge orifice or conduit bywhich the dust and chaff may be delivered at some other point, as may bedesired.

A machine embodying my said invention will be first fully described, andthe novel features thereof then pointed out in the claim.

Referring to the accompanying drawings, which are made a part hereof andon which similar numerals of reference indicate similar parts, Figure 1is a perspective View of a threshing machine having a pneumaticstraw-stacker provided with my present invention; Fig. 2, a View, partlyin side elevation and partly in central section, of a pneumatic strawstacker and the attachment thereto embodying my present invention,together with a fragment of the separator upon which the same ismounted; and Fig. 3, a detail sectional View, on an enlarged scale,similar to a portion of Fig. 2.

The threshing-machine or separator 1 and the pneumatic straw-stacker,including the fan-housing 2 and the fan therein, the conduit 3, leadingfrom said fan-housing, the neck at, and the telescopic sections of thetrunk or chute 5 and 6, together with the means for operating the same,are or may be, generally speaking, similar to the corresponding portionsof a machine of an ordinary and wellknown form and will not, therefore,be further described herein, except incidentally in describing theinvention.

Connected to the portions 5 and 6 are the suction-tubes 7 and 8, whichare correspondingly telescopic, as shown. The'hood to the pneumaticstraw-stacker, instead of being attached wholly to the section 6, as isusual, is widened out and comprehends and covers the ends of both thesections 6 and 7. Said hood may be of any ordinary or desiredconstruction. It is shown as composed of the pivoted sections 18, 9, and10, united by a pivot 1.1 and normally held downwardly by a spring 12and adapted to be raised upwardly by a cord or rope 13. A fan 14. ismounted at some suitable place on the separator 1, and the eye thereofis connected to the lower end of the telescopic part 8 by a flexibletube 15. The fan-housing 14 contains an ordinary suction-fan, as will bereadily understood, and this is driven by a belt 16 from some suitablepoint on the machine. The fan-housing 14 preferably has a delivery-tube17, which generally leads down to the bottom of the strawstack, wherethe dust and chaff, separated from the straw by means of my invention,are deposited in a pile by themselves.

Having thus fully described my said invention, what I claim as new, anddesire to secure by Letters Patent, is I The combination, with apneumatic strawstacker, of a supplemental exhaust-fan, and a tubeleading from the eye of said fan to and connected with the trunk orchute of the straw-stacker, whereby a portion of the air driven throughsaid trunk or chute may together with the dust and chaff intermingledtherewith be drawn back and discharged at a separate point, while thestraw is thrown out onto the stack in the ordinary manner, substantiallyas set forth.

In witness whereof I have hereunto set my hand and seal, at Peoria,Illinois, this 23d day of February, A. D. 1899.

GEORGE W. KRAMER.
